STRANGE-Music CDs pop in,mount then disappears from Desktop/iTunes

I am experiencing the almost exact same phenomenon, except the disk does not even show up for a moment. Every other music cd I insert just disappears, doesn't register in itunes (set to automatically import it, then eject it), or the finder. Based on your description, I checked disk utility and was at least able to see and eject it there, rather than rebooting every time.
I don't think age of the cd has anything to do with it, I have a broad range, and this is my second intel iMac, my previous one (1 year older, 20" also a white iMac) never had any issues with any of my cds, and I am working with the very same disks. Something's funky. A driver issue, mayhap? My old iMac was on 10.4.x, this one is on 10.5.x.

Cheers -

I'm seeing the same symptoms on my MacBook Pro. Mounting the CD in Disk Utility works, and then I found that disconnecting my external FireWire drive let the CDs mount normally from the get-go. So, if you have an external drive plugged in (I have a Lacie), try disconnecting it.

hi i'm in australia with my new 24 inch imac -
same problem!

I was hoping the 10.5.2 update would fix this problem, but it just happened again, twice: pop in CD, it gets the info from Gracenote, then unmounts. It's annoying to have to go to Disk Utility to mount CDs. C'mon, Apple!

I don't have anything mounted and I am having the exact same problem, I have a new MBP 15", everything is updated. I even tried turning off the "eject auto" to see if this made a difference. I just have to hit the eject button on the computer and then re-insert and the CD mounts.

FYI- I have been playing around, if you actual "quit" the application itunes and then insert the CD, it mounts on the first time, otherwise it mounts and then unmounts. It also does not matter what settings you have in itunes for importing nor do the CD/DVD settings effect it. It is an itunes problem and/or bug.

I have the same issue with my G4 mac mini. The disc will appear momentarily then unmount. I can then mount it by going to Disc Utililty and mounting it there. It doesn't happen every time, I'd say around 25% of the time. I just upgraded to version 7.6.1 and I'm having the same issue.

I'm having the EXACT SAME PROBLEM.

Please let me know if anyone finds a solution.

Thanks.

I have been having the same problem. It seems that after importing one or two CDs, the problem begins and requires Disk Utility every time to mount the CD before importing. What gives?

I am having the same issues. I just took the time to import about 400 CD's and let me tell you . . . this problem s u c k e d. When I called the local store to inquire about it - of course they said it would NEVER happen.

Anyway, I've taken a few notes and have narrowed down a few things that seem to "aggravate" this problem and/or make it happen over-and-over again. Here's a quick rundown . . .

1. HEAT - the hotter the machine, the more often it'll happen. As I write this, I've been importing music for about 4 hours. Of the last 25 or so CD's I inserted, only 2 mounted properly. When it's really hot (heat-soaked) it'll happen every time. When the CD's come out they are really hot.
2. CHEAP CDROM's - Almost every CD that I can see through a tiny bit when held up to the light will fail to mount initially. Older/thicker ones mounted more often - until iMAC got heat-soaked.
3. REBOOT TIME - yes . . . I actually said it. In my case, if I reboot (cold machine) then I can import about 12 or 15 CD's before the problem occurs. However, if I have imported 20 or more - then let machine cool off for a few hours, the problem is still there (acting non-heat-related). A quick reboot clears it up for the next 8 or 10 cd's - then it's back to the problem.
4. XMAS MUSIC - Apparently iTunes hates Christmas Music.

My hunch is that there is a timing/wait setting (or error-checking mechanism) that needs to be tweaked a bit. Maybe the faster processors and/or drive uncovered it or something.

I don't know - I just know that my initial thought that I could insert a CD and walk away has been incorrect.

How many people have to report something before it actually becomes an issue that the developers will look at? I'm a bit disappointed with my first iMAC purchase - I hope this isn't reflective of all of the hardware and software.
